LE ROY D. KEEHN, or CHICAGO, LLINoIs.

SHOE-SOLE PROTECTOR.

Application filed May 31,

To all 'whom 'it may concern.' 1

Be it known that l, Ln Rev D. Kamin, a citizen or' the United States of America, and a resident of Chicago, in the county ot Cook and State ot Illinois, have invented a certain new and nsetull Improvement in Shoe-Sole Protectors, of which the follow* inn` is a specification.

This invention relates to that type oi' protectors for slice soles in which metallic wear plugs or the like are embedded in the material of the shoe sole, and exposed at the surface of said sole to al'ord wear resistingn properties thereto. And the, present improvement has for its object:

To provide a structural formation and arrangeinentof parts and features whereby metallic wear stiuds or brads of a headed torni inserted obliquely into the shoe sole and troni the exposed edge thereof, to protect said edge, and with the gradual wear ot parts in use, provide a gradual exposure of the lowerinost portions of the studs or brads commensurate with such wear of the slice sole, all as will hereinafter more fully appear.

In the accompanying drawings:

Fig. l is an under perspective view of a shoe having the present improvement applied,

Fig. 2, is a bottom view of the front part ot a shoe sole with a similar application.

F 3, i and 5, are companion detail l vertical sections, illustrating the progressive steps in the application ot'the invention to a shoe sole.

Figs. G and 7, are side elevations of the headed brad used in carrying ont the inveiition.

Lilie ieterence numerals parts in thc several views.

As represented in the drawing', the wear resisting` elements of the present invention consist of headed brads, cach having a main shank portion l, one end of' which is tapered to a point, with said point split longitudinally to provide clinching tangs 2 in the inal driving operation of the brad into position. The other end of the shank l. is

indicate like 1924. Serial No. 716,960.

formed with a head d, the outer surface of which is ot a crown or convex forni, while its inner surface is of a cone form merging into the end of the shank 1 as shown.

In carrying out the present invention a plurality of holes 4 bored in the outer sole and partly into the middle or inner solo ot the shoe in an oblique direction trom the front and lower vexposed edge ot said outer sole, as shown more particularly in Fig. 3. A stud or brad ot the before de- .;cribed formation is driven into a 'hole 5, and in reaching` the partially ornied eXtension of said holein the middle orinner' sole ot the shoe, the points oleach brad separates laterally to cause a clinching` of the brad in place. In such driving of the stud or brad into place the material ot the outer solevadjacent to the headedl portion of the stud or brad is displaced downwardly from the tread surface ot the outer sole, illustrated in Fig. 4, and the inal operation then consists in grinding,` away such downwardly projecting` part of the outer sole and any depending; portion of the stud head, to a plane even with .the tread surface of the sole.

The inventionris more particularly designed for use on the toe portion of the shoe sole, the scope of the invention however einbraces an application in manner above described to a side edge of the shoe sole as illustrated in Figs. l and 2.

Having thus fully described iny invention what I claim as new and desire to secure `by Letters Patent, is

A shoe having` a sole provided with an obliquely inclined opening extending from the lower edge of the solo, in combination with. a wear resisting means comprising stud fitting' said opening and having a conilil form head at one end of its shank and a `v split point at the. other end adapted to' spread apart in a inal driving operation on the stud.
